Abstract

The invention relates to vehicles for transporting persons and/or goods, which vehicles travel on roads or alternatively on rails and at least partially use electrical energy using electric motors as drive units, wherein the electrical energy used is predominantly or substantially produced within the vehicle by converting kinetic energy, in particular components of the kinetic energy that are caused on the vehicle bodywork as gravitation effects and components of the kinetic energy from curve centrifugal forces and acceleration motions of the vehicle body, the vertical dynamic acceleration motions of the wheels and wheel suspensions, and other components, wherein the electrical energy generated in such away is temporarily stored in chemical energy stores (batteries) and/or other suitable storage media, for example, high-power capacitors or flywheel stores, until the electricity is used in the vehicle drive motors and/or other loads.

Description

11 Power Recovery Suspension System for Hybrid and Electric Cars "

P A T E N T A N M E L D U N G

The automotive industry is currently experiencing strong political and economic pressure to achieve the required CO2 limit of 120 g / km, which should at least be achieved by 2015 as a "fleet average".

Given the well-known inevitable end of oil production in sufficient quantities, possibly in 20-30 years at the latest, and a development period of at least 10 years for series-production electric cars, it will be high time for the industry to abandon the outmoded combustion engine technology and efficiency unprofitable wrong way to give up hydrogen engine, because electric drives are in many ways the ideal solution for motor vehicles.

While it is true that the newly planned by the industry electric cars still have significant deficiencies, namely insufficient power storage capacity of the batteries used and consequent insufficient driving range.

There are currently other disadvantages, such as high weight and volume of lithium-ion batteries with enormous manufacturing costs and currently still uncertain lifespan and far too long recharge of several hours. There will be significant improvements and technical advances in the near future. Nevertheless, the basic battery problems remain the electric cars, unless completely new ways of energy optimization with in-vehicle power generation in electric cars are taken to compensate for these problems, at least partially, which is the aim of this invention.

A well-known method of recovering kinetic energy while driving in Elektroauato is the generator function of the drive motor during braking. The amount of energy so recuperated is relatively low.

This invention offers the possibility of supplying energy to the hybrid and electric cars in a novel manner and in a considerable amount while driving by an in-vehicle, self-sufficient energy conversion from conversion of kinetic energy present during driving, in particular from relevant components of the gravitational and centrifugal energy Electricity. There are many variations of the technical implementation of this invention. In this description, only a few advantageous, preferred variants are shown. All other conceivable and derivable versions are also the subject of this invention and derived therefrom property rights.

For this purpose, reference is made on the one hand to the subordinate claims and on the other hand to the following explanations of the preferred embodiments. In this case, those advantageous embodiments of the inventive idea should be included, resulting from any, variable combination of sub-claims and methods, as well as those without drawing.

In the drawings, with the omission of details which are known to the person skilled in the art, or according to the teachings disclosed in the cited prior art patents and publications may be considered known as schematic, simplified representations of preferred embodiments of the inventive devices and Method shown.

Under "electric vehicle" or "electric car / hybrid car" are not only passenger cars (cars) to understand, but also all other single- or two-lane road transport such as trucks (trucks), buses and two-wheeled vehicles such as bicycles with electric assist motor, electric scooter or electric motorcycles, and tricycles, electrified wheelchairs, etc. At least in part, various portions of the described teachings, systems of the invention, components, and technical procedures may also be employed in military vehicles, such as tanks and other military vehicles, including trailers.

Possible and also included in this invention and the claims is the at least partial use of invention components in a suitable and modified form or variation in rail vehicles such as railways, trams, subways, elevated trains, magnetic levitation trains (Transrapid) or even in mining vehicles, etc.

In the patents and publications US 4 032 829 from 22.08.1975, US 5 578 877 from 13.06.1994, DE 295 18 322 Ul from 18.11.1995, US 6 952 060 B2 from 07.05.2001, DE 102 20 846 Al from 08.05 .2002 and WO 2005/089347 A3 Shock absorbers are described for motor vehicles that generate electricity during compression and rebound of the vehicle wheels suspension by so-called linear generators integrated in the shock absorber. The mode of operation is in principle technically and physically identical to the known rotary generators for power generation and is known in the art, which is why a more detailed description is dispensed with.

These are the first approaches to power generation through the conversion of kinetic energy and gravitational energy, which acts on the vehicle body during driving. The electricity is generated here by the vertical movements of the wheels while driving in these "generator shock absorbers".

A disadvantage of these and similar inventions that the yield of electricity with an estimated maximum of 5% is relatively low, because by design, only a very small part of the force acting on the vehicle gravitational energy can be absorbed and converted into electricity energy. The main part of the gravitational energy is taken up by the tires with their flexing movements, the negative acceleration energy of the resilient wheels (weight) and the suspensions of the suspension and convert the respective acting components of the gravitational energy largely into useless and unwanted acceleration forces of the body (Up and down movements) or heat energy that is released to the atmosphere.

This is where the main inventive concept of the present invention, whose main goal is an energy self-sufficient vehicle with in-vehicle energy, so as to equip the electric vehicle with sufficient energy capacity to compensate for the previous insufficient in-vehicle storage capacity and thus the main disadvantage of today's hybrid electric car designs after Prior art, namely lack of travel range and the very long reload time of the very expensive and voluminous power storage elements (batteries / capacitors) to eliminate.

Another enormous economic advantage and for car owners very positive side effect of this invention is that the operating costs (gasoline, diesel, gas and maintenance with oil change) almost completely eliminated or significantly reduced. In further development of the state of the art for the generation of electricity from the conversion of kinetic and gravitational energy according to the above-cited prior art and analogous inventions, according to the invention the novel technologies for generating electricity from gravitation and kinetic energy (horizontal centrifugal force, vertical acceleration) described below are proposed as follows:

1. Electricity generation by principally known linear generators, which are in the inner radius of the vehicle wheels, preferably coupled to the suspension or tilted in or on the vehicle body almost vertical or at any suitable angle and while driving by the gravitational vertical movements of the wheels or the body On a guide rail freely movable actuator (magnetic element) of the linear generator in the electromagnetic field of a spatially surrounding stator vertically moved up and down which according to the known laws of induction electricity is generated, which is passed to the battery and / or high-power capacitors and stored there.

2. Electricity generation by linear generators, which are arranged at a suitable location in, on or under the vehicle body almost horizontally with the action axis 90 degrees to the vehicle longitudinal axis (direction of travel), with an on a guide rail freely movable actuator of the linear generator in the surrounding electromagnetic Field of the stator is moved by the force acting in curves on the body centrifugal force, whereby electricity generated, is forwarded to the battery for temporary storage.

3. Electricity generation by linear generators, which are arranged at a suitable location in, on or under the vehicle body almost horizontally with axis of action zero degrees to the vehicle longitudinal axis (direction), with a freely movable on a guide rail actuator (magnetic element) of the linear generator in the surrounding Electromagnetic field of the stator is moved by the force acting on the body kinetic energy (positive and negative accelerations) when accelerating or braking the vehicle, whereby electricity is generated, which is forwarded to the battery and stored there. 4. Electricity generation by linear generators, which are arranged at a suitable location in, on or under the vehicle body, and their in the electromagnetic field of the stator on a linear guide movable actuator (magnetic element) of the linear generator with suitable mechanical, hydraulic, pneumatic or suitable combined and designed devices of the above-mentioned type, of which at least one actuator is coupled to a vehicle wheel or its suspension and while driving through the unevenness of the road surfaces with the corresponding accelerations by gravity, the respective movements record or match and congruent the / the actuator (s) in the moved or move electromagnetic field and thus generate or generate electricity that is passed to the battery and stored there. A detailed technical functional description is shown in the preferred embodiment described below.

The following describes by way of example an inventive system for generating electricity in the vehicle by converting kinetic energy and gravity, which produces a multiple of electricity energy compared to the known linear generators, which are integrated in conventional automotive shock absorbers, as mentioned above.

In this context, the state of the art for so-called "Active suspension or suspension systems" for motor vehicles to quote. These are, inter alia, the publications DE 102 13 156 A1, DE 42 12 839 A1, DE 103 30 344 A1, DE 38 44 803 C2, DE 41 18 823 A1, DE 43 34 227 A1, DE 41 20 758 A1, DE 36 31 876 Al, DE 41 14 783 A1, DE 38 23 044 A1, DE 195 21 747 A1, DE 42 21 088 A1, EP 0 284 053 B1, EP 0 470 991 B1, EP 0 681 533 B1, EP 0 470 166 Bl, EP 0 371 709 B1, EP 0 569 429 B1, EP 0 470 993 B1, EP 0 471 734 Bl

The hitherto usual vehicle suspension consists per wheel of a force acting on the suspension steel spring with a non-adjustable hydraulic shock absorber. This construction is called "passive suspension system".

In addition, there are so-called "active hydropneumatic suspension", which consist of a differential cylinder, a gas pressure accumulator as a spring element with a constant or electronically controllable throttle as Dämpferlement with control valve and fixed displacement pump. The latest, improved developments are suspension systems, which are called "fully active suspension". Here, the existing suspension components steel spring and hydraulic shock absorber are replaced by an electronically controlled actuator, which affects the suspension characteristics in many ways by the KommandosignaIe the control electronics, thereby significantly improving the vehicle's roadholding.

These include a level control, rapid readjustment of the lifting movements of the wheels, adjustment of dynamic forces to prevent nicks and rolling of the body, change the damping effect (hardness of the suspension) and so on. The main advantage of these designs is the variable electronically controllable change in the suspension characteristics, which results in a significantly improved road holding and thus improved driving safety.

The fundamental systemic disadvantage is that the forces acting on the bodywork as the result of the vectors from the kinetic energies of the vertical vehicle movements which are for the most part components of the gravitational forces acting through road bumps are not used to derive power therefrom. Instead, these energies are uselessly converted into heat by the springs, damper elements, chokes, etc. or, in part, as unwanted vehicle motions, namely, primarily in vertical accelerations of the body.

A first, but completely insufficient step to convert these kinetic and gravitational energies into electricity and use are the above-cited inventions shock absorbers with integrated linear generators or rotation generators. However, their efficiency is estimated to be only a maximum of 5%, as the majority of the gravitational energy applied to the vehicle is destroyed by the vehicle springs or hydraulic throttle valves of the shock absorbers.

Starting from the state of the art, the object of this invention is to develop these known active suspension suspension systems in a novel manner by replacing the ultimately energy-dissipating components steel spring, hydraulic shock absorbers, throttle valves, etc. by a system which, on the one hand, has the suspension and damping functions as in the past On the other hand, realizing "active" systems can convert nearly all kinetic and gravitational energy components to nearly 100% into electricity.

The following is a schematic representation of the general function of generating electricity by kinetic energy and gravitation. Of the multiple variable constructions some preferably suitable embodiments are described, wherein the known in the prior art technical and physical principles are not addressed or described in detail, since they can be taken from the literature and cited references if necessary.

Furthermore, a simplified description is used insofar as, for example, the illustration "the pump increases the pressure" or the "valve switches", etc. means that these processes are electronically activated by the higher-level control electronics (16) and / or an associated microprocessor is deactivated according to the algorithm stored in the programming without this being explicitly mentioned.

All described and conceivable variants of the various devices and their functions and methods in the embodiments apply mutatis mutandis to all other embodiments and also in the non-described possible variants, even if not explicitly indicated in the description. Fig.l and Fig.2 show a first embodiment as a principal, identical and schematic vertical section of a vehicle wheel (1) with a suspension (4) which is fixed to the joint (4b) on the body (3) and a suspension element (2). with integrated linear generator (7) in the novel construction according to the invention. This spring element (2) not only takes over the known functions of suspension and damping as in the conventional coil spring and the hydraulic shock absorber and all other functions of the above-mentioned improved version of the "active suspension systems" but also additionally realizes the power generation according to the invention by the occurring during driving vertical Wheel movements and their kinetic energy as components of the gravitational force acting on the vehicle. In contrast to the previously known constructions so spiral spring or air spring elements and shock absorbers completely eliminated.

The suspension element (2) is connected at the lower end by a hinge (4a) to the suspension (4) and connected at its upper end by the suspension strut suspension (3a) with the upper part of the body (3). Inside there is a current-producing linear generator (7) consisting of the stator (8), the actuator (11) and the actuator guide (6a). The stator (8) consists of current-carrying windings, and preferably has an inner cylindrical cavity in which the actuator (11) is preferably attached as a cylindrical member to the actuator guide (6a) and when moving the actuator guide (6a) within the stator magnetic field with a minimum air gap can slide up and down and thus produced by induction electricity.

The actuator (11), which can be moved vertically together with the pressure pistons (KO.1) and (KO.2), may alternatively also consist of current-carrying windings or may be designed as a suitably shaped and dimensioned permanent magnet. The actuator guide (6a) is connected in its further course with the piston rod (6), which carries the pressure piston 1 (KO.1) at the opposite end. The pressure piston 1 (KO.1) is part of the hydraulic spring and damper element (5) named as pressure cylinder 1 (DZ.1), which has at least two, optimally four pressure chambers (DK.1 / DK.2 / DK.3) , The under pressure piston 1 (KO.1) located part of the pressure cylinder 1 (DZ.1) is named as a pressure chamber 1 (DK.1), the above the pressure piston 1 (KO.1) located part of the pressure cylinder 1 (DZ.1 ) is referred to as pressure chamber 2 (DK.2). By means of at least one sealing ring (IIa) mounted on the pressure piston (KO.1) both pressure chambers 1 (DK.1) and 2 (DK.2) are separated from each other by hydraulic pressure.

The housing of the suspension element (2) and the linear generator (7) are preferably cylindrical and with guides, such as sliding guides (2c) ball or roller bearings, or preferably linear ball bearings mounted telescopically against each other and sealed with at least one sealing ring (IIa), so that in inner space of the two housing parts, a third pressure chamber 3 (DK.3) is formed.

The actuator guide (6a) and the piston rod (6) are guided in at least two guides (2a / b). At least three hydraulic lines (9a / b / c) lead into the at least three pressure chambers (DK. L / DK.2 / DK.3). In an improved embodiment, at least six hydraulic lines are provided, three for supply and three for discharge of the fluid, whereby a faster pressure change is ensured by the increased flow rate of the fluid.

All the same features and functions will not be described again in the other versions. FIG. 3 shows a further, improved version of the exemplary embodiment which, in contrast to FIGS. 1 and 2, has two pressure pistons 1 (KO.1) and 2 (KO Hereby, instead of three, a total of four pressure chambers 1 to 4 (DK.1 / DK.2 / DK.3 / DK.4) can be realized, which gives even better technical possibilities, which are presented below. In this embodiment, for each pressure chamber DK. l / DK.2 /DK.3/DK.4) one hydraulic line each (9. la / 9 lb / 9.2a / 9.2b). 4 shows by way of example a pneumatic system, or preferably a hydraulic circuit diagram with control electronics (16) and the various sensors and four hydraulic supply lines (9.1a / 9.1b / 9.1c / 9.1d) and four hydraulic discharge lines (9.2a / 9.2b /9.2c/9.2d). The pressure supply takes over at least one hydraulic pump (P.1), which is preferably an oscillating pump with a downstream pressure booster (34). Here are many variants possible, for example, for cost reasons instead of the four hydraulic pumps shown only one or two can be used, in which case the hydraulic lines and the valve system is modified accordingly.

The at least one linear generator (7) is in this case centrally between the two double pressure chambers 1 and 2 (DK. L / DK.2) and 3 and 4 (DK.3 / DK.4) with the associated pressure piston 1 (KO.1) and 2 (KO.2) arranged (Figure 3) wherein the respective piston rods (6.1) and (6.2) are connected to each other and the center of which the actuator (11) of the linear generator (7) is fixedly mounted.

Alternatively, two linear generators (7) may also be provided on the outer sides of the at least one double pressure chamber 1 (DK.1) located therebetween and optionally the double pressure chamber 2 (DK.2).

The basic function of the suspension element (2) with integrated linear generator (7) shown in Figure 3 and Figure 4 is as follows. From a suitable hydraulic high pressure pump (P.4) hydraulic fluid is pumped into the pressure chamber 1 (DK.1) via at least one hydraulic line (9.1a). As a result, the piston 1 (KO.1) is raised from its bottom dead center (UT.1) in the direction of the vector (VB).

When he has traveled the way (Xl), the mean (ML.1) has been reached. A displacement sensor (Sl) reports this to the control electronics (16), which then gives the command to stop the supply of hydraulic fluid through a check valve (Vl). At this moment, the piston 2 (KO.2) is in its top dead center (OT.2) because the housing of the impression cylinder 2 (DZ.2) is loaded with the force of the negative Vertikalvec- tors (VG), which at a four-wheeled vehicle, depending on the axle load distribution corresponds to about 25% of the vehicle weight. The valve (Vl.2) is opened and hydraulic fluid is pressed into the pressure chamber 4 (DK.4). The pressure piston 2 (KO.2) is pushed down to the middle position (ML.2). When it is there, the piston distance (A) is reached, which corresponds to the working position of the two pressure pistons 1 (KO.1) and 2 (KO.2). Here, however, the actual movement is not a downward going of the piston 2 (DKO.2), since this can not move in this direction due to the back pressure of the piston 1 (DKO.1) with sufficient hydraulic pressure, while the housing of the pressure cylinder. 1 (DZ.1) is supported against the roadway via the joint (4a) with the wheel suspension (4) and the vehicle wheel (1). If the hydraulic pressure force in the pressure chamber 1 (DK.1) is identical to the negative force vector (VG) is the actual direction of travel (stroke) by the piston 2 (KO.2), the way (Yl) in the vertical upward, whereby the housing of the suspension element (2) is raised and thus via the suspension strut suspension (3a) Body (3) in the vertical around the way (Yl) lifts.

The functions described can be carried out not only sequentially but preferably also simultaneously to increase the speed of work readiness. With a corresponding design of the hydraulic system with suitable seat valves, this is not necessary at every journey, since the hydraulics can maintain this basic pressure position. This is known prior art and is not shown in detail.

The two pressure pistons 1 (KO.1) and 2 (KO.2) now have the working distance (A) and both are in their respective center position (ML.1) and (ML.2) .Also the actuator (11 ) is in its middle position (ML3) and expediently has the same positive and negative lift heights (X1 + X2 / Y1 + Y2) as the pressure pistons 1 (KO.1) and 2 (KO.2)

In this context, it is pointed out that any mechanical or hydraulic force on one of the two pressure pistons (K0.1 / K0.2) and any positive or negative acceleration and distance traveled on the other pressure piston (KO.1 /KO.2 ) and the actuator (11), since all three components are mechanically firmly connected to each other by the piston rods (6.1 / 6.2). In the further description of the embodiments, this is not explicitly stated, but assumed to be known.

The travel path and the respective positions of the two pressure pistons 1 (KO.1) and 2 (K.2) as well as the motion-congruent actuator (11) constantly monitor at least one suitable sensor, which is preferably an electronic displacement sensor (WS), which constantly monitors the Current position of the two pressure pistons (KO.1 / KO.2) registered between the respective upper and lower dead center (OT / UT) and the control electronics (16) reports.

Below the description of the operation of the novel suspension element (2) with the inventive functions suspension, shock absorption, active suspension control and simultaneous power generation by the integrated linear generator (7) in the embodiment of FIG. 3 as a so-called "shock absorber".

If it is expedient for certain reasons, the various functions according to the invention can also be realized in technically different combinations by separate components.

For example, if the linear generator (7) is to be designed to be more powerful and thereby has a larger volume and weight, or if several, at least two vehicle wheels (1) are to deliver their kinetic energy to a common linear generator (7). Or if instead of a linear generator (7) at least one rotary generator (29) is used which is driven by at least one hydraulic motor (33) which is installed in the body.

When the vehicle is being driven, the vehicle wheel (1) is moved upward in the vertical direction by a positive path (W.vert), for example due to an uneven road surface. (Fig.11)

This movement is a force and thus kinetic energy, which is a resultant of acting on the vehicle body earth gravity. The vertical path (W.vert), symbolized in the drawing of FIG. 11 in the part of the vector (VB) (FIG. 3) as a positive vertical acceleration of the vehicle wheel (1), is transmitted to the suspension element (2) via the wheel suspension (4). transferred and acts with the exerted positive vertical force (K.vert.pos) on the impression cylinder housing (DZ.1) and in the hydraulic pressure chamber (DK.1) located hydraulic fluid. The force (K.vert.pos) in FIG. 11 acts on the pressure piston 1 (KO.1) due to the hydraulic fluid at at least the same high counter-pressure in the pressure chamber 1 (DK.2) of the pressure cylinder 1 (DZ.1). and is transferred from this to the piston rods (6.1) and (6.2) and the pressure piston 2 (KO.2). Since the printing cylinder 1 (DZ.1) is mounted mechanically vertically displaceable over a pressure-tight bearing (IIa) relative to the outer housing of the suspension element (2), the pressure cylinder 1 (DZ.1) is moved vertically upward by the acting suspension movement of the suspension (4). (X2 in Fig.3)

Since the pressure chamber 2 (DK.2) via the housing of the printing cylinder 2 (DZ.2) is mechanically firmly connected via the spring strut housing (2) and the bearing (3a) with the body (3) of the vehicle, here works a negative vertical Counterforce, depending on the axle load distribution, with about 25% of the vehicle weight, which is symbolized in the drawing Figure 3 as Vector (VG).

If the pressure chamber 4 (DK.4) is depressurized or an electronically controlled, lower pressure force is exerted on the pressure piston 2 (KO.2) than the positive vertical force (K.vert.pos), the pressure piston 2 (KO .2) upward in the direction (Yl) to its top dead center (OT.2). This movement simultaneously carries out on the piston rods (6.1) and (6.2) fixedly mounted actuator (11) of the linear generator (7) and thus moves in the magnetic field of the stator (8), which is induced in accordance with the known laws of physics, the forwarded, processed and at least partially cached until use in a battery.

This movement of the actuator (11) in the magnetic field of the stator (8) causes known according to the laws of physics, a counter force (K.mag) against the direction of movement of the actuator (11). This counterforce (K.mag) is proportional to the magnetic field strength and in principle performs the same function as the conventional hydraulic shock absorbers and the associated coil spring have. In addition, the strength of the damping effect at any time by the control electronics (16) can be changed by, for example, the magnetic field strength of the stator (8) and / or optionally. Actuator (11) is varied by electronically controlled variation of the current / current amplitude and thus magnetic field strength in the stator (8) or optionally in the actuator (11), provided that this is not a permanent magnet but produces the magnetic field with a current-carrying coil. This is known prior art, which is why no detailed description is required. At least one pressure sensor (DS) per pressure chamber (DK.x) supplies the necessary information to the control electronics (16). At least one displacement sensor (WS) constantly monitors the positions of the pressure pistons 1 (DK.1) and 2 (DK.2) and this reports the control electronics (16), which uses these parameters for the switching algorithms of the pneumatic valves.

If the magnetic damping effect by the magnetic counterforce (K.mag) should not be sufficient, just before reaching the top dead center (OT.2) or before in any other position by the control electronics (16), the current / current amplitude of the Stator (8) flowing current can be increased, whereby the magnetic field amplified and congruent to the magnetic counterforce (K.mag) is increased and / or by supplying hydraulic fluid via the hydraulic line (9.2b), the positive vertical movement (Yl) of the pressure piston (KO .2) are braked, that is to say dampened and finally stopped, whereby this too can be varied and metered very quickly and sensitively by the control electronics / microprocessor (16) via suitably designed throttle valves.

Likewise during movement of the pressure piston 1 and (KO.1) and 2 (KO.2) and the actuator (11) in the opposite direction, the negative vertical movement. Here also the control electronics (16) the current / current amplitude and thus the magnetic field strength and thus the magnetic opposing force (K.mag.) Vary as needed electronically. In addition, if necessary, the damping effect during the movement of the pressure piston 2 (KO.2) a metered counterforce by variable hydraulic pressure can be established by supplying hydraulic fluid into the pressure chamber 3 (DK-3) of the pressure cylinder 1 (DZ-I). However, these measures should be activated only in exceptional cases, since this corresponds in principle to the technical function of the usual hydraulic shock absorbers and accordingly energy is useless destroyed, since it is not converted into electricity in the linear generator (7).

Controlled by the control electronics (16), realize the pressure chambers 1 (DK.1) and 2 (DK.2) of the printing cylinder 1 (DZ.1) essentially the functions of the "active chassis", while the impression cylinder 2 (DZ.2 ) with its pressure chambers 3 (DK.3) and 4 (DK.4) in cooperation with the linear generator (7) in the main fulfill the suspension and damping functions of the system with simultaneous power production. The vertical oscillating movements of the actuator (11) in the magnetic field of the stator (8) cause with appropriate physical design and dimensioning a magnetic counterforce (K.mag) to the respective direction of movement, which in principle has the same effect and function as the usual suspension components coil spring and Shock absorber during compression and rebound of the vehicle wheels (1). The pressure chamber 4 (DK.4) carries the proportionate weight.

During compression of the vehicle wheel (1), the pressure piston 2 (KO.2) moves vertically from its center position (ML.2) in the direction of the top dead center (OT.2) .This movement direction (force vector VB) acts on the actuator ( 11) induced magnetic counterforce (K.mag) of the respective direction of movement of the actuator (11).

As soon as the pressure piston 2 (KO.2) reaches the top dead center (OT.2) or if the compression force (W.vert pos) has previously been compensated by the counteracting magnetic force (K.mag) of the actuator (11) and thereby the pressure piston 2 (DK.2) is stopped before the top dead center (OT.2), the pressure piston 2 (KO.2) must come back to its position center position (ML.2) again to perform a new, sufficient spring movement can. (Fig.11 B / C). This happens because the control electronics (16) receives information from at least one suitable sensor, for example a pressure, or preferably displacement sensor (WS), that the pressure piston 2 (KO.2) has been stopped and has reached its point of reversal. Then, a hydraulic valve is opened, whereby the hydraulic fluid is fed into the pressure chamber 2 (DK.2), whereby the pressure piston 2 (KO.2) is moved downward in the negative vertical direction (Y.2).

At the same time, the pressure chamber 3 (DK.3) is largely depressurized by opening a hydraulic fluid drain valve. This and the pressure supply to the pressure chamber 4 (DK.4) moves the vehicle wheel (1) and thus the pressure piston 2 (DK.2) downwards to its middle position (ML.2). As soon as this is reached, which the center position sensor (S.1) informs the control electronics (16), the pressure piston 2 (DK.2) is stopped in this position by stopping the hydraulic fluid supply into the pressure chamber 4 (DK.4) , This must now hold as much pressure as corresponds to the Vector body weight (VG) and carry this weight. At the same time, the pressure chamber 3 (DK.3) is held without pressure for rapid reactions during rebound movements of the vehicle wheel (1). If a further sensor, preferably a pressure sensor (DS.x), determines that the wheel (1) must continue to rebound in order to have firm contact with the road, this rebound movement can be continued until the pressure piston 2 (DK) 2) reaches bottom dead center (UT.2).

Also in this downward movement of the pressure piston 2 (KO.2), the actuator (11) is on the one hand generating electricity and on the other hand with its magnetic induced counterforce (K.mag) shock-absorbing effect. If the pressure piston 2 (KO.2) reaches its bottom dead center (UT.2) and an even further rebound of the vehicle wheel (1) should be required, the pressure chamber (DK.2) of the pressure cylinder 1 (DZ. 1) reduced in pressure or depressurized. At the same time, the pressure in the pressure chamber 1 (DK.1) can be increased. In addition, the way (X.2) for rebounding the vehicle wheel (1) is available.

In this case, however, no power generation of the linear generator (7) is given. The springback functions are identical in the reverse order.

At the same time, the hydraulics realize the spring action of the conventional steel spring in the vehicle suspension (4), that is, the compensation of the static load by the vehicle weight (negative-vertical Vector VG) by the pressure (force) in the hydraulic chambers 1 (DK.1 ) to 4 (DK.4) are each at least as large as the weight that arises per vehicle wheel (1).

From Figure 3 it can be seen that the structural components Duckzylinder 1 (DZ.1) with pressure piston 1 (KO.1), piston rods (6.1 / 6.2) and pressure cylinder 2 (DZ.2) with pressure piston 2 (KO.2) take in their interaction according to the invention, the support and suspension functions of the usual steel springs and in addition by the algorithms of the control electronics / microprocessor (16) allow further options in the sense of a so-called "active chassis". These functions are state of the art, but without the novel inventive technical possibility of simultaneous power generation by integrated or alternatively external, spatially separated, hydraulically or mechanically coupled power generators, which may also be located inside or on the outside of the body, the as described, may be suitably designed, coupled linear generators (7) or alternatively may be at least one rotary generator (29) which is mechanically, pneumatically or preferably hydraulically driven by a hydraulic motor (33) and thus produces electricity.

A level control can also be easily realized at any time by appropriate programming of the control electronics (16). This is done by changing the working distance (A) of the pressure piston (KO.1) and (KO.2), in each case for the two wheels of a vehicle axle. If, for example, the load on the rear axle of the vehicle is heavier due to loading, the working distance (A) is reduced by the load change due to the load force (b). By pressure increase in the pressure chamber 1 (DK.1) and / or pressure reduction in the pressure chamber 2 (DK.2) and / or alternatively pressure increase in the pressure chamber 4 (DK.4) and / or pressure reduction in the pressure chamber 3 (DK.3 ), the distance (B) is again made congruent with the distance (A) and thus reaches the same level again.

Furthermore, it is also possible, for example, to lower the body at high-altitude distance to the road surface when driving on freeways, by electronically controlling the pressure piston clearance (Xl), preferably depending on the speed.

This has the advantage that thus the vehicle's center of gravity is lower, thereby improving the roadholding of the vehicle. In addition, this, in conjunction with certain aerodynamic measures, reduces aerodynamic drag, that is to say, the "cw value" and the energy consumption influenced by it.

Another optimal possibility is the compensation of centrifugal forces when cornering by changes in body height from the two outer wheels to the inside of the curve by, for example, the spring struts (2) of the inside wheel suspension (4), the working distance of the pressure piston (X1 / X2) proportional to the speed or the effective centrifugal force is variably reduced and / or in the struts (2) of the outer wheel suspension (4), the working distance of the pressure piston (X1 / X2) is variably increased in proportion to the speed or the effective centrifugal force. Further functions are the compensation of rolling and pitching movements of the body through corresponding identical electronically controlled suspension strut activities, which the control electronics (16) can activate by means of appropriate programming algorithms and control commands.

These basic functional sequences are prior art, especially in similar constructions of the known active hydropneumatic chassis systems.

In Figure 5, a further preferred variant is shown as an exemplary embodiment. This construction is characterized by a particularly compact design, because the actuator (11) by its special construction simultaneously assumes the function of the pressure piston 1 and 2 (KO.1 / KO.2). As can be seen in FIG. 5, the pressure pistons 1 and 2 (KO.1 / KO.2) together with the actuator (11) form a common component.

This compact design, inter alia, has the advantageous possibility of mounting the suspension and shock absorber element (2) with integrated linear generator (7) in the region of the inner cavity of the vehicle wheel rim (22), as shown by way of example in FIGS

7 is a simplified partial perspective view of a vehicle wheel (1) with suspension element (2). Construction and function in this varied version of the further embodiment are analogous to the above embodiments, differences being essentially in Figures 5 and 6 are as follows:

In the preferably cylindrical housing of the suspension element (2), a hollow cylindrical stator (8) is installed. In the inner cavity of the hollow cylindrical stator (8) has a smooth cylindrical surface-like inner wall (23) is arranged, which consists of a material which is permeable to magnetic fields. In the inner cavity of the cylindrical stator (8) there is also the cylindrically shaped actuator (11) having a cylindrical inner cavity through which the round Aktuatorführungs- rod (IIb) is guided, with its lower and upper end in the respective camps ( llc) which are parts of the impression cylinders 1 (DZ.1) and 2 (DZ.2). At the lower end of the actuator (11) is mechanically fixedly connected to this, the pressure piston 1 (KO.1) and at the upper end, also mechanically firmly connected, the pressure piston 2 (KO.2) arranged. Both pressure piston 1 and 2 (KO.1 / KO.2) wear at their inner and outer radii at least one sealing ring (IIa), the precise guide and pressure seal against the inner sliding wall (23) of the stator (8) and the cylindrical outer surface of the actuator guide (IIb) guaranteed. Since the actuator (11) as shown in Figure 6 is immediately apparent, in its height dimension is significantly shorter than the inner cylinder space of the stator (8), thereby the pressure chamber 1 (KO.1) is the pressure chamber 1 (DK.1) and above the pressure piston 2 (KO.2) the pressure chamber 2 (DK.2) is formed. In this lead at a suitable location, the associated hydraulic lines (9.1a / 9.1b and 9.2a / 9.2b)

With appropriate hydraulic fluid supply into the two pressure chamber chambers 1 and 2 (DK.1 / DK.2) with electronically controlled pressure change, the two pressure pistons 1 and 2 (K0.1 / K0.2) slide together with the mechanically fixedly coupled actuator (11) and from, which generates electricity in a known manner by induction. The other functions result in the same sense from the properties and functions of the other variants described above.

Fig.5 and Fig.6 show a further variation as a preferred embodiment. A modification of the versions shown in Figure 3 is possible by the pressure cylinders 1 (DZ.1) and 2 (DZ.2) are carried out without the linear generator located in a separate housing (7) and only the above-described hydraulic functions for suspension , Damping, active suspension, etc. exercise.

The at least one linear generator (7) is thereby laid in a suitable position on, under or in the body (3) and via hydraulic lines (9ff) with the at least two pressure cylinders 1 and 2 (DZ.1 / DZ.2) per vehicle wheel (1 ) coupled energetically (hydraulically).

The two pressure pistons 1 and 2 (K0.1 / K0.2) form a common component that separates the two pressure chambers (DK.1) and (DK.2). This variant has the advantage that at the same distance from the upper and lower support legs (20a) (Figure 6) (total length of the actuator guide) by the elimination of the actuator (11) has a lower height of the piston unit (K0.1 / K0.2 ) and thus a larger stroke (travel) and lower weight results. The proportionate vehicle weight (VG) is here by the from the hydraulic pump (P.1) via the hydraulic line (9.1a) and a one-way check valve (14) filled with hydraulic fluid pressure chamber 1 (DK.1) and the existing there, the same high back pressure (Vp.1) recorded and constantly monitored by the pressure sensor (DS.1). See Fig.4 Example hydraulic-electronic circuit diagram

During a compression movement (VB) of the vehicle wheel (1) vertically upward, the hydraulic pressure (K.hydr) in the pressure chamber (DK.1) increases. This is registered by the pressure sensor (DS.1) and when a limit value is exceeded, the control electronics are activated (16) a control valve (12a) in the hydraulic line (9.1b) free, which leads first to a hydro-pneumatic high-pressure accumulator (15) and from there by hydraulic lines (9.x) to the linear generator (7), preferably in the type described to Fig.5 is executed.

The release of the control valve (12a) leads on the one hand to a pressure reduction in the pressure chamber 1 (DK.1) and on the other hand, the hydraulic fluid is passed through a one-way check valve (14) in at least one hydropneumatische high-pressure accumulator (15) and stored there under the corresponding pressure .Or preferably guided via the bypass line (9c) in the pressure chamber 2 (DK.2).

The pressure reduction in the pressure chamber 1 (DK.1) occurs only up to the lower pressure limit, which corresponds to the proportionate vehicle weight (VG) until the compensation of the equivalent hydraulic counterforce (K.hydr) is reached and the center position (ML.2) of the piston 1 and 2 (KO.1 / KO.2) is restored.

The at least one hydropneumatic high-pressure accumulator (15) can be provided individually for each vehicle wheel (1) or alternatively it can also be designed and used for a plurality of vehicle wheels (1), ie their hydraulic spring and damper elements (5).

From this hydropneumatic high-pressure accumulator (15), the hydraulic line (9.1b) via a further control valve (12b) and at least one pressure booster (34) to the at least one linear generator (7) which is preferably designed for example in the type shown in Figure 5, or alternatively to at least one hydraulic motor (33) having at least one Rotation generator (29) drives, wherein by an electronically controlled shuttle valve (12b) via the hydraulic lines (9.1a) and (9.1b) from the hydropneu- matic high pressure accumulator (15) under high pressure hydraulic fluid hydraulic chambers 1 and 2 (DK.1 / DK.2) in the linear generator (7) is alternately fed, whereby the pistons 1 and 2 (KO.1 / KO.2) high frequency back and forth, which then in a known manner by the coupled actuator (11) for inductive Power production, which is stored in a suitable storage medium (battery / capacitor). About the hydraulic discharge lines (9.2a) and (9.2b), the excess hydraulic fluid is returned to the hydraulic reservoir (13).

Further advantages of this embodiment are: It can affect the kinetic energy of at least two or more vehicle wheels (1) on only one linear generator (7), which brings performance and cost advantages.

In addition, the unsprung masses in the vehicle wheels (1) are reduced and the linear generator (7) can be larger in size and therefore give more power, so generate more power.

Alternatively, in this construction, instead of the at least one linear generator (7) and at least one rotary generator (29) are used, which is driven by at least one hydraulic motor (33), the required hydro-energy, that is, hydraulic pressure from the pressure cylinders 1 and 2 (DZ.1 / DZ.2) generated from the components of kinetic and gravitational energy of the relative movements of the body and at least one vehicle wheel (1).

Alternatively, instead of hydraulic fluid possibly a pneumatic system with gaseous pressure media may be partially used and / or at least partially mechanical transmission elements are used or varied, suitable system combinations of hydraulics, pneumatics and / or mechanics are used.

FIG. 6 shows a further varied application example. Here, a vertical partial cross-section and in FIG. 7 a perspective section of a vehicle wheel (1) are shown with a wheel hub (21), a wheel rim (22) with built-in wheel hub motor (19) of known design, for example according to patent GB 2 440 251 . (State of the art) On the outside of the wheel hub (21), as usual, the wheel rim (22) screwed .On the opposite inner side of the wheel hub (21) is a suitably designed and dimensioned carrier (20) is mounted, at its upper and lower end depending preferably angled cantilevered support leg (20a) protrudes. Between the upper and lower support legs (20a), the actuator guide (IIb) is mounted vertically, in a 90 degree position to the central axis of the wheel hub (21). If required, this can also be tilted with its upper end in the direction of the rear of the vehicle by some suitable angle degrees be arranged to improve the tracking.

The actuator (11) can optionally be designed as a suitably dimensioned and shaped permanent magnet or consist of current-carrying windings which deliver the required electromagnetic field. The actuator (11) forms, as described with reference to FIG. 5, together with the pressure pistons 1 (KO.1) and 2 (KO.2), a mechanically fixed component and, in turn, as a hollow cylindrical double pressure piston (KO.1 / KO.2 ) whose functions are in principle identical as shown in Figure 5 and described in detail.

In contrast to the version described with reference to FIG. 5, here the movable actuator (11) is provided, which is likewise provided on its top and bottom with a respective pressure piston 1 (KO.1) and 2 (KO.2) , via a stable support (4) mechanically fixed to the vehicle body (3). Thus, the spring movement of the vehicle wheel (1) by the up and down movement of the holder (20) together with the actuator guide (11 b) in the storage (llc) and the actuator (11) mounted pressure piston 1 (KO.1) and 2 (KO.2)

For example, when the actuator (11) is made with electric windings, the actuator guide (Hb) may be made of a suitable magnetized material, thus giving off a magnetic field as a permanent magnet. Alternatively, the stator (8) may be as shown in FIG , the actuator (11) surrounded radially as a hollow cylindrical member with coil function.

The pressure cylinders 1 (DZ .1) and 2 (DZ.2) shown in the drawing Fig.6 with their pressure chambers 1 (DK.1) and 2 (DK.2) work in principle the same meaning as in the previous embodiments described above, in particular to Fig.5. The difference and Advantage of this design is that here the steering axis (LA) of the vehicle wheel (1) coincides with the central axis of the actuator guide (IIb).

Thus, it is also possible to construct a simple and relatively inexpensive all-wheel steering. The steering movement can here conventional (mechanical) with steering linkage or electro-motor ("steer by wire") are performed. This principle is a principle known technology and can be used alternatively.

The embodiments of the invention described above use components of kinetic energy and gravity from the relative vertical movements between body (3) and vehicle wheel (1) in the suspension for conversion into electrical energy.

Another possibility according to the invention for in-vehicle energy generation is the conversion of kinetic energy components from positive and negative acceleration forces, for example when driving the vertical body movements, when braking the horizontal negative accelerations in the direction of travel and in curves the centrifugal forces acting on the body ( 3) act.

For this purpose, special linear generators (7) are provided in the vehicle whose axes of action (central axes) are in the vertical and the horizontal, the horizontal axes of action of the linear generators (7) on the one hand in the vehicle longitudinal direction (direction) and on the other hand alternatively in 90-degree position are arranged to the vehicle longitudinal direction.

The linear generators (7) used are constructed similar to the embodiment shown in Figure 5 and may have any suitable length. The design of the linear generator (7) and actuator (11) may be cylindrical with a round cross section and a suitable diameter or a cubic component having a rectangular, polygonal or any other shaped cross section.

The intended for this purpose embodiment of the linear generator (7) has an actuator (11), which is arranged for example by a ball circulation bearing on the guide (IIb) very smoothly movable and by the weight of the actuator (11) can follow the acceleration and / or centrifugal forces acting on it and behaves freely swinging and thus performs a linear movement in the magnetic field of the stator (8) and thereby produces electricity.

A significant improvement in the efficiency is achieved when the linear generator (7) has a pressure-tight housing and the housing interior almost a vacuum prevails, whereby the movements of the freely oscillating actuator (11) are less inhibited.

In the horizontal attachment of the linear generator (7) in 90-degree position to the vehicle longitudinal axis for detecting the (centrifugal) centrifugal forces, the actuator (11) can be freely oscillated between the two end positions by the centrifugal forces acting.

In the vertical attachment of the linear generator (7) and in that attachment in which the axis of action coincides with the vehicle longitudinal axis, the freely oscillating actuator (11) must be expediently brought into a central position (ML) again as soon as it reaches one of the end positions Has. This can be done mechanically by suitably dimensioned springs or caused by magnetic opposing forces of opposite-pole permanent magnets or by electric magnetic coils which are mounted in the two end positions on the actuator guide (IIb) which are automatically activated when the end position is reached.

Alternatively, but with higher technical and cost, this can be the same as described above in the Radfedersystemen even with electronic control pneumatically or hydraulically identical.

In addition, for a better understanding of the basic operation of the above-described hydraulic suspension and damping element (2) in the conversion of kinetic energy from components of gravity into electricity by an integrated or mechanically, alternatively hydraulically coupled generator, preferably linear generator (7) is a graphical representation in a simplified, not to scale form shown as Fig. 11 and Fig.12 and the principal function as described in more detail below. This invention employs a novel vehicle suspension and damping system which does not employ any of the hitherto conventional energy-dissipating elements (steel spring or pneumatic bellows and hydraulic shock absorbers) but preferably a particular hydraulic suspension and damping element according to the invention which is fitted with a suitable power generator located in a separate housing. preferably a linear generator (7) mechanically or hydraulically coupled or combined as a common unit.

To avoid mistakes it is pointed out that this technology is obviously not a "perpetuum mobile" or even a direct conversion of gravitation into electricity. Because the energy required for the production of electricity is constantly supplied externally in sufficient quantity in the form of the hitherto unused kinetic energy of the vehicle wheel spring movements, which is converted into electricity. Whereby this kinetic energy is a resultant of the vehicle weight, which is known by the earth Gravity is caused.

In that regard, this novel inventive technology is quite an indirect conversion of components of the gravitational forces that physically realize in the vehicle weight, in electricity with the help of the linear generator (7) recorded kinetic energy from the previously unused wheel spring movements.

Although it eliminates the conventional steel springs or air bellows, including hydraulic shock absorbers. Their well-known technical functions including level control and "active chassis" remain intact. The suspension and damping element (2) with integrated current generator (7) thus converts kinetic energies of the resilient vehicle wheels (1) the components of the vehicle weight as the result of gravity are in significant quantity with very good efficiency in electricity to. The amount of electricity produced with this is congruent to the vehicle weight.

The higher the weight, the greater the current efficiency. At a total vehicle weight of, for example, two tons at the spring movement on each vehicle (1) a (weight) force of about 500 kg, which even with relatively low suspension strokes constantly caused by road bumps, large amounts of electricity can be generated, depending according to weight and constructive design. The electricity energy obtained here can be determined with a simplified theoretical consideration as an approximate average value as follows. The variable parameters suspension stroke of the vehicle wheels, effective force amplification by mechanical and / or hydraulic power amplifiers, dimensioning and efficiency of the linear generators, energy losses due to transmission elements, etc. are not taken into account for simplicity or considered as a constant.

In an electric vehicle with, for example, two tons total weight and four wheels each with one of the linear generators according to the invention, the energy thus generated per kilometer traveled is calculated as follows:

Assuming that each of the four wheels on average has a suspension travel of +/- 10 mm per decimeter of the traveled distance, a suspension stroke of 200 m per wheel is calculated for a distance of one kilometer. The total suspension stroke for all four wheels is thus 800 m per kilometer. With the assumed weight of 500 kg (approx. 5,000 N) per vehicle wheel (1) acting as kinetic energy on the linear generator (7), the energy assumed in the above assumptions is 4,000,000 Nm (4 MNm) per kilometer. These are approximately 1.1 kWh per kilometer. With (unrealistically high) 50% energy conversion losses applied, at least 0.5 kWh / km or 50 kWh remain on 100 km of driving.

This is more than sufficient energy not only for the electric drive motors but also for the auxiliary heating, air conditioning, etc. which can be cached in batteries and / or capacitors.

As an example of the average amount of electricity required for the drive motor of an electric car, the already developed for series production "Tesla Roadster" Tesla Motors USA, called. The 3-phase asynchronous motor used there 185 kW power has a power consumption of 12 to 18 kWh per 100 km driving distance (average 133 Wh / km).

As already mentioned, the system can not only fulfill the usual suspension and damping functions with an appropriate design, but also a vehicle level regulation and all other possibilities of a so-called "active chassis" for Elimi- ning, rolling, rolling and rolling movements of the body in a highly efficient manner. In addition, even when cornering a body inclination to the inner curve radius can be realized. In varied version can be easily integrated a four-wheel drive and four-wheel steering. See, for example, Fig.7

11 shows the movement of the vehicle (3) in the direction of travel (FR). In position (A) begins the Fahrbahnerhöhung (FB.1) which extends to the position (C). The vehicle wheel (1) moves over the distance (A> C), whereby the path (A> B) causes a deflection of the wheel.

In the position (B), the vehicle wheel (1) reaches the highest point or the maximum compression travel.

The forces acting here are progressively increasing as the vectors (K.vert.pos) represented. These act against the weight, shown as Vector (G.norm) via the suspension element (2) with the variable hydraulic pressure on the vehicle wheel (1 ) is exercised. In the course (B> C), the vehicle wheel (1) makes a rebound movement and in the position (C) again reaches the normal plane of the roadway (FB).

Both in the compression movement and in the rebound movement of the vehicle wheel (1), current is generated in the coupled linear generator (7) in a known manner by induction.

If the damping effect by the magnetic counterforce (K.mag) of the linear generator (7) in the power production is insufficient, the vehicle wheel (1) makes some weakening post-spring movements, which are absorbed and damped by the elastic vehicle tire.

Too large vertical residual forces of the jounce movement and insufficient damping by the tire, the body (3) from its normal body height (H.norm) is raised vertically to the supernormal body height (H.pos) whereby the excess residual energy is destroyed.

During the movement of the vehicle wheel (1) from the position (A) to (B) it moves vertically upward, whereby the hydraulic pressure is increased, because the additional force (K.ver.pos) on the impression cylinder (DK-4) is exercised.

This is registered by the displacement sensor (WS) and / or the pressure sensor (DS) and communicated to the control electronics (16). This gives the pressure reduction signal or switches the associated pressure chamber (DK.4) without pressure via the valve. Thus, the compression movement (K.vert.pos) of the vehicle wheel (1) can take place without resistance and the activated linear generator (7) can convert the total kinetic energy during compression to almost 100% in electricity until the vehicle wheel (1) the position (B) has reached.

According to the known physical induction laws in the linear generator (7), this current production generates the magnetic counterforce (K.mag), which acts in the opposite direction to the compression movement as a force vector and damps it until the speed and movement in the position (B) is zero ,

The damping effect due to the magnetic counterforce (K.mag) can be controlled very rapidly in a wide range by the control electronics (16) by means of a variable regulation of the current intensity and the resulting magnetic field. Depending on the stored parameters and switching algorithms, the field strength can be varied as desired, as a result of which the suspension identification (damping intensity) and thus the suspension characteristics and road position can be adapted very quickly and automatically to the requirements.

Upon further movement of the vehicle (3) in the direction of travel (FR) from position B to C, the vehicle wheel (1) again springs from the maximum position B until it reaches the normal plane of the roadway (FB) in position C.

This rebound movement is also used to generate electricity and is caused by the dead weight (gravitational force) of the vehicle wheel (1) and its components (tires, rim, hub, brake, Radaufgängung). The effective forces are shown symbolically in the graph Fig.11 with the vectors (K.vert neg).

If necessary, the control electronics (16) by the hydraulic pressure in the respective associated pressure chamber (DK.x) the rebound positively or negatively affect (accelerate or decelerate) which has a positive or negative effect on the overall efficiency in the power generation of the system accordingly, as this Hydraulic braking corresponds to a conventional "shock absorber function" and thus reduces the amount of power production.

At the same time optimally a pressure and volume equalization between the pressure chambers 4 (DK.4) and 3 (DK.3) is provided by a hydraulic bypass line (9c) which in each case of need from the control electronics (16) with a check valve mounted therebetween (14 ) is opened or closed, so constantly in both pressure chambers 4 (DK.4) and 3 (DK.3) there is an equal pressure, which corresponds to the proportionate vehicle weight, which rests on the suspension element (2). The advantage here is that less hydraulic energy is lost through this design and the overall efficiency (amount of electricity) is much higher, since the hydraulic pump (Px) has to re-pump less hydraulic fluid but only the energetic flow losses in the lines and at the valves (pressure losses / flow resistance) compensated.

When the vehicle wheel (1) has reached the position C, the normal force, the vector weight (G.norm), acts on it. The Vector weight (G.norm) per wheel is about 25% of the total vehicle weight with the same axle load distribution. In this power generation system for the efficiency of a higher vehicle weight is beneficial. In the case of a small-surface roadway increase or decrease, at least two linear generators (7) are activated when driving over in their respective front and rear wheels. If the increase or decrease extends over the total width of the road surface or at least the vehicle width (track width) all linear generators (7) in all four Fahrzugrädern (1) are activated.

The distance C to D is the Nachfederbereich if any kinetic residual energies are still present, which were not sufficiently attenuated. In the area C to D, the vehicle wheel (1) may still have the tendency to spring down further. This prevents the now flat roadway (FB) from having to be compensated by the hydraulics either by the control electronics (16) and / or the tire of the vehicle wheel (1) absorbs these forces and deforms and / or the vehicle body is undesirably raised from the normal height (H.norm) positively (vertically) to the height (H.pos). The thereby effective vertical-negative forces cause the tire of the vehicle wheel (1) continues to keep in contact with the road surface (FB) and does not lift off briefly, which would otherwise be detrimental to driving safety.

In the case of tire deformation and vertical body movement, of course, the associated kinetic or primary component of the gravitational energy is lost for power generation with the linear generators (7), so optimally the programming (algorithms) of the control electronics (16) must be designed to is avoided.

In the alternative case, when the vehicle wheel (1) passes through a roadway depression or pothole (route E to G in FIG

Fig.12), the function of power generation is basically identical.

12 shows the movement of the vehicle wheel (3) in the same direction of travel (FR). In position E, the roadway lowering (FB.2) begins which extends to position G. The vehicle wheel (1) moves over the distance (E> G) with the vehicle wheel (1) executing a rebound movement on the way (E> F).

In position F, the vehicle wheel (1) reaches its lowest point or the maximum rebound travel. The forces acting here are progressively larger than the vectors (K.vert.neg). In principle, the kinetic energy of the coupled linar generator (7) can be converted into electricity, the total force (G.norm), represented as the vectors (K.vert.neg) corresponding to about 25% of the total vehicle weight the linear generator (7), which then converts these kinetic or the associated components of the primary gravitational energy into electricity, wherein the current generated in the current magnetic counterforce (K.mag) ("Lorentz force") counteracts this rebound motion and a motion-damping effect exerts the principle which corresponds to a conventional hydraulic shock absorber and beyond of the control electronics (16) in its effect (damping force) can be adjusted very quickly and in a wide range variable and needs by electrical modulation of the current and thus the congruent according to the physical laws magnetic field strength and dependent magnetic countercurrent ft ("Lorentz force") •

When the vehicle wheel (1) has reached the position F receives the control electronics (16) through the displacement sensor (WS) and pressure sensor (DS) the information that the rebound movement is completed.

The control electronics (16) then switches the associated hydraulic chamber (DK.4) (FIG. 3) without pressure so that the subsequent compression movement on the line F to G is almost without hydraulic resistance and the linear generator (7) releases the kinetic energy Forces of the vector (K.vert.pos) with an optimum efficiency of almost 100% to generate electricity.

At the same time, the hydraulic bypass capacity (9c) is opened, which in turn results in the pressure and volume compensation of the hydraulic fluid in the two pressure chambers 3 (DK.3) and 4 (DK.4). The fluid is thus passed from the pressure chamber 4 (DK.4) to the pressure chamber 3 (DK.3), at the same time the pressure P (P.hydr) remains constant, which by the control electronics (16) by means of the pressure sensors DS.3 and DS.4 is monitored.

When the position G is reached, the vehicle wheel (1) is again on the normal road surface (FB). The compression movement (K.vert.pos) must be terminated here by the spring forces were damped by the magnetic induction counterforce (K.mag) to zero, otherwise on the track G to H Nachfeder- movements of the vehicle wheel (1) would be done, which would be detrimental to the road conditions of the vehicle (3). The control electronics (16) must therefore by appropriate variation of the current strength of the coil current in the linear generator (7) the magnetic counterforce (K.mag) the respective requirements entprechend adapt to the gain or attenuation of the induced magnetic counterforce (K.mag) to ensure that the compression movement of the vehicle wheel (1) is completed in or shortly before the position G so that the wheel does not rebound or even lifts but remains on the road surface.

If this magnetic damping (K.mag) should not be sufficient in exceptional cases, the control electronics (16) can actively suppress the unwanted Nachfedern by appropriate hydraulic counter-pressure measures (pressure increase in pressure chamber DK.4) due to electronic activation compensatory counter forces (K.hydr) the Destroy residual energies and slow or stop the jounce movement.
